$tan (\frac{π}{2})$ $tan(pi/2)$ is not defined.

Explanation:

You can find it out whwn you try to calculate it using identity

$tan x = \frac{sin x}{cos x}$ $tanx=sinx/cosx$

For $x = \frac{π}{2}$ $x=pi/2$ the denominator of this expression is zero, so it cannot be calculated.

$tan (\frac{π}{2})$ $tan(pi/2)$ is undefined

Explanation:

In general the $tan$ $tan$ of an angle based on the unit circle in standard position is defined to be $\frac{y}{x}$ $y/x$ where $(x, y)$ $(x,y)$ is the coordinate of the terminal point of the radial arm.
